Many large power generators use hydrogen
gas as a coolant. Hydrogen has low density and very good thermal conductivity.
It can carry away the heat produced in a generator and thus allow the generator to
operate at a higher power output.
The Nova Model 436 is an excellent choice
for continuous monitoring of the hydrogen atmosphere in a generator. It offers
the following analysis ranges:
Range 1: 0-100% Hydrogen in Air
Range 2: 0-100% Hydrogen in CO2
Range 3: 0-100% Air in CO2
This model is similar to the portable Model
380 mentioned in this post. When a generator shutdown is scheduled,
it is recommended that the continuous analyzer is used to monitor the purge
process, while a portable analyzer is also connected and used as a back-up
monitor.
We have been asked recently by some power
companies to consider offering an additional interesting feature to the Nova
Model 436.
In some cases, an unsafe condition has
developed when the continuous H2 purity analyzer has been accidentally switched
to the wrong range and left to operate that way. The analyzer will now be
looking for an incorrect combination of gases and will not report a reliable
result. Because H2 purity is an important parameter to monitor during normal
generator operation, the analyzer should remain set to the correct range for
reliable results.
Would this feature be of interest to you?
To ensure that the purity range is
activated at all times during normal generator operation, an explosion-proof
lock-enabled switch can be provided. The purity range would be always locked
on, and only a key could disable it and enable the purge ranges. The key would
stay in the slot during purge, and only be removable when the purity range is
selected again. Perhaps the key would be kept in the supervisor’s office when
not in use.
If this is of interest to you, contact Nova
for details.
